Answer: 9kgm/s
Explanation:
Given that,
Mass of ball = 3 kg
Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?
Since momentum refers to the quantity of motion of the moving ball,
Linear momentum = Mass x Speed
= 3kg x 3m/s
= 9 kgm/s
Thus, the linear momentum of the ball is 9kgm/s
I'm not sure tbh, but if it helps, heres a game that helped me understand bases acids and neutrals for chem in 8th grade! http://static.lawrencehallofscience.org/scienceview/scienceview.berkeley.edu/html/showcase/flash/jui... I know it looks cheesy, but it helps! Chem is something youll have until college, and it helps to learn about it. You can make drinks using acids, bases, and neutrals!

Answer: The copper wiring most likely caused the mini-refrigerator fire.
Explanation: A mini-refrigerator may have one or more evaporator fan motors. These motors have copper wiring. In some situation these copper wires gets overheated. It may result to the firing of the mini-refrigerator.
Therefore, the mini-refrigerator fire was most likely caused by copper wiring.
